This document discusses how library catalogues can be used as readers' advisory tools through collaboration between cataloguers and readers' advisors. It highlights how enriched catalogue records, including genres, subjects, and annotations, allow readers to more easily find similar titles to those they enjoy. The integration of tools like NoveList Select directly into catalogues provides reading recommendations. Social catalogues and folksonomies further enhance catalogues by incorporating user-generated tags, reviews, and lists. This improves the user experience and engages readers with the library collection online.
